Abstract

Elastomeric roofing strip (thickness 1.5 - 2.0 mm.) is produced from a mixt. contg. (in wt. %): ethylene-propylene-diene polymer 20-80, polyethylene 20-40, polyisobutylene 5-20, bitumen 20-30, and a filler 10-30. This material has high tensile strength and good resistance against atmospheric agents. It can be protected against biological attacks by addn. of 0.1-0.5% of phenyl-beta-naphthylamine.

Description

Dichtungsbahn aus elastomerem Werkstoff Die Erfindung bezieht sich auf eine Dichtungsbahn aus elastomerem Werkstoff zur Abdeckung von Gebäuden. Sealing Sheet Made of Elastomeric Material The invention relates to on a sealing membrane made of elastomeric material for covering buildings.

Für die Abdeckung von Bauwerken sind Dichtungsbahnen aus verschiedenen elastomeren Werkstoffen bekannt.For the covering of buildings, waterproofing membranes are made of various elastomeric materials known.

Diese Dichtungsbahnen bestehen zum Teil aus vulkanisierten Kautschukmischungen. Solche Bahnen erfordern einen verhältnismäßig hohen Arbeitsaufwand für die Herstellung. Andere Dichtungsbahnen bestehen aus thermoplastisch verformbaren Elastomeren, wie beispielsweise PVC oder Polyäthylen. Diese Bahnen sind verhältnismäßig wirtschaftlich herstellbar; sie haben jedoch den Nachteil, daß sie gegen Temperatureinflüsse empfindlich sind und darüber hinaus einen erheblichen kalten Fluß aufweisen.Some of these geomembranes consist of vulcanized rubber compounds. Such tracks require a relatively high amount of work for the production. Other sealing sheets consist of thermoplastically deformable elastomers, such as for example PVC or polyethylene. These railways are relatively economical manufacturable; however, they have the disadvantage that they are sensitive to the effects of temperature and also have significant cold flow.

Aufgabe der Erfindung ist es, eine Dichtungsbahn auf Elastomerbasis zu erstellen, deren Hersjellung verhältnismäßig einfach ist und mit Maschinen durchführbar ist, die für Gummibahnen gebräuchlich sind. Die Anforderung an die Temperaturführung ist daher relativ gering. Andererseits soll aber eine hohe Strukturfestigkeit bei dem Bahnmaterial erreicht werden, ohne daß eine Vulkanisation mit allen seinen Begleiterscheinungen erforderlich ist.The object of the invention is to provide a sealing membrane based on elastomers to create, the production of which is relatively simple and feasible with machines which are in use for rubber sheets. The requirement for temperature control is therefore relatively low. On the other hand, it should have a high structural strength the web material can be achieved without vulcanization with all its accompanying phenomena is required.

Zur Lösung dieser Aufgabe ist erfindungsgemäß vorgesehen, daß bei der Dichtungsbahn der elastomere Werkstoff aus folgendem Gemisch besteht: 20 bis 80 Gewichts % Äthylenpropylendien-Polymerisat (EPDM), 20 -40 Gewichts 5' Polyäthylen, 5 - 20 Gewichts % Polyisobutylen, 2o - 30 Gewichts % Bitumen und Io - 30 Gewichts % Füllstoff.To solve this problem, the invention provides that at the sealing membrane of the elastomeric material consists of the following mixture: 20 to 80% by weight ethylene propylene diene polymer (EPDM), 20-40% by weight 5 'polyethylene, 5 - 20% by weight of polyisobutylene, 2o - 30% by weight of bitumen and Io - 30% by weight % Filler.

Je nach den Anforderungen können die Anteile der vorstehend genannten Bestandteile in den angegebenen Grenzen variiert werden. Die Variation richtet sich in erster Linie nach dem vorgesehenen Verwendungszweck.Depending on the requirements, the proportions of the aforementioned Components can be varied within the specified limits. The variation is directed primarily according to the intended use.

Die optimalen Anteile liegen jeweils etwas unterhalb der Nittelbereiche in den angegebenen Prozentwerten.The optimal proportions are each slightly below the mid-range in the specified percentages.

Eine derartige Dichtungsbdin zeichnet sich durch eine vereinfachte Herstellung und durch eine außerordentliche Festigkeit und Unempfindlichkeit gegenüber außeren Einflüssen aus.Such a sealing strip is characterized by a simplified one Production and by an extraordinary strength and insensitivity to outside influences.

Vorzugsweise kann für EPDM ein Typ mit langen Polyäthylenketten zur Anwendung gelangen. Das zur Mischung zugegebene Bitumen weist vorzugsweise einen Erweichungspunkt von 85/25 auf. Zur Steigerung der Beständigkeit gegen biologische Einflüsse kann dem Gemisch o,1 bis o,5 Gewichts % Phenyl-ß-naphthylamin (PBN) zugesetzt werden.A type with long polyethylene chains can preferably be used for EPDM Application. The bitumen added to the mixture preferably has a Softening point of 85/25. To increase the resistance to biological Influences can be added to the mixture from 0.1 to 0.5% by weight of phenyl-β-naphthylamine (PBN) will.

Die bevorzugte Wandstärke dieser Dichtungsbahn liegt im Bereich zwischen 1,5 - 2,o mm. Diese Wandstärke reicht für die meisten Anwendungsfälle- völlig aus. Die Verlegung der Bahn wird bei dieser Wandstärke verhältnismäßig einfach durchführbar, da sie auch die erwünschte Elastizität aufweist.The preferred wall thickness of this sealing membrane is in the range between 1.5-2.0 mm. This wall thickness is completely sufficient for most applications. The laying of the membrane is relatively easy to carry out with this wall thickness, because it also has the desired elasticity.

Die Erfindung wird in Verbindung mit einer Abb. beispielsweise beschrieben. Die Abb. zeigt einen Querschnitt durch eine Dichtungsbahn 1, die zur Verlegung auf einem Dach geeignet ist. Die Bahn hat eine Breite von vorzugsweise 1,80 m. Ihre Wandstärke beträgt 1,7 mm. Der Aufbau der Dichtungsbahn ist wie folgt: Die elastomere Masse enthält 20 Teile EPDM, 20 Teile Polyäthylen, 22 Teile Bitumen, io Teile Polyisobutylen und 28 Teile Füllstoff. Ferner ist o,2 5' PBN zugesetzt. Bei diesem Aufbau weist die Dichtungsbahn folgende physikalische Eigenschaften auf: Zugfestigkeit nach DIN 53504 längs mehr als 50 kp/cm2 quer mehr als 70 kp/cm Bruchdehnung nach DIN 535o4 längs 600 5' quer 500 96 2 Weiterreißwiderstand nach DIN 53363 längs mehr als 6 kp/cm quer mehr als 8 kp/cm Schlitzdruckprüfung nach DIN 16935 kein Durchtritt Härte Shore A ca. 74 spez.

The figure shows a cross section through a sealing membrane 1, which is to be laid on a roof is suitable. The web has a width of preferably 1.80 m Wall thickness is 1.7 mm. The structure of the sealing membrane is as follows: The elastomeric The mass contains 20 parts EPDM, 20 parts polyethylene, 22 parts bitumen, 10 parts polyisobutylene and 28 parts of filler. Furthermore, 0.25 'PBN is added.
